Fuel Cell Components and Principle of Operation


50% of the weight of the Flora

Relatively easy to extract from

Organic Municipal Solid Waste (MSW)

Paper

Wood chips

Cellulose agricultural wastes

Why Glucose ?

Glucose is the first stable product in photo-synthesis

Glucose is the building block in all the Saccharides:

Fructose, Maltose, Lactose,

Starch,

Cellulose.

Existing Microchip Electro-Chemical Nanochamber,

developd as a sensor, will be adapted to perform

as a Glucose Fuel Cell


Conclusions

7 Parallel Investigation Activities are taking place

in the College:

Next Year, we hope that we will be able to present

the advances in this Activities, in the next Braude

Conference or in a dedicated FC Conference
